Abstract

Die Waage weist einen an Lenkern (14, 15) parallelgeführten Lastaufnehmer (16), eine Wägezelle (9) und dazwischen mehrere Uebersetzungshebel (7, 17) auf. Dem unmittelbar auf die Wäge­ zelle (9) einwirkenden Uebersetzungshebel (7) ist ebenfalls ein mit Lenkern (3, 4) parallelgeführter Lastaufnehmer (5) zugeordnet. Dadurch lässt sich der mit der Wägezelle (9) zusammenwirkende Uebersetzungshebel (7) und der diesem zuge­ ordnete Lastaufnehmer (5) zusammen mit der Wägezelle zu einer baulichen Grundeinheit (1) vereinigen, die eine selbständige Waage niedriger Nennlast darstellt und in den übrigen mecha­ nischen Teil (13 bis 20) der für eine höhere Nennlast bestimmten Waage eingesetzt ist. Auf diese Weise kann die Serienfabrikation von Waagen flexibler und wirtschaftlicher gestaltet werden. Am zusätzlichen Lastaufnehmer (5) kann sich der Kraftangriffspunkt für ein zuschaltbares Kalibriergewicht (23) befinden. Es ergibt sich damit eine von der Lage des Kalibriergewichts unabhängige Krafteinleitung in den an den Lastaufnehmer (5) angekoppelten Uebersetzungshebel (7).
